All babies are offered the meningococcal vaccine for immunisation against group B and group C meningococcus - with the new MenB vaccine and MenC vaccine. Adolescents are, in addition, offered immunisation against meningococcal group W (MenW) - in MenACWY. Also, if you go to certain countries, in particular Saudi Arabia and countries in sub-Saharan Africa, you should be immunised against various strains of the meningococcus before you travel. You should be immunised at least two weeks before you travel if you need this immunisation.
